    Our Thermal Wall Insulation Process

    INFO

    What is Thermal Wall Insulation ?

    Thermal wall insulation adds a continuous layer of insulation to the exterior of suitable walls on UK homes.

    Heat loss through external walls can make a property harder to heat. External wall insulation can help reduce heat loss by adding a layer of insulation to the outside of suitable walls. 

    External wall insulation systems can be installed on a range of suitable substrates, subject to a proper assessment of the existing wall construction and condition. Whether your home has solid walls without a cavity, brickwork or blockwork, we can recommend and install a suitable external wall insulation and render system. 

    The system helps reduce heat loss, helping your home stay warmer and more comfortable during the colder UK winter months. This can help reduce heating demand and may contribute to lower energy bills.

    Here is the procedure. Our team carries out a property survey to assess the building and recommend a suitable insulation and render system. Once the quotation and system have been agreed, the team begins installing the insulation boards to the external walls. This also involves attaching the basecoat adhesive and anchor fixing pins on the boards. Then, we cover it with a reinforced basecoat incorporating alkali-resistant glass-fibre mesh.

    Then comes a second thin base coat. We apply it before the final decorative finish coat, which could be Silicone, Acrylic, and Monocouche. This layered system helps reduce heat transfer through the external walls.

    Thermal Wall Insulation

    There are many types of boards, which include EPS (lightweight), Phenolic (high thermal performance at lower thickness), and Mineral Wool (non-combustible/mineral-based option). All come in different thickness sizes ranging from 20mm to 200mm with different thermal conductivity (λ-value). 

    Landlords, private property owners, and commercial building owners have now started to take U-values more seriously than ever. Reducing heating costs and carbon emissions are important considerations for many property owners. 

    Selecting an insulation material with an appropriate thermal conductivity (λ-value), together with the correct thickness, can help achieve the required thermal performance.

    A super fast and efficient response from David who actually took the time to see the property rather then other contractors who rather lazily wanted a photo. Kept me informed along the whole process and his team were quick and clean. Would use again and would recommend!

    Had both front and back of the house rendered with acrylic silicone. A very professional job by a very hard working team who did not stop. David was professional in organising everything and the price was very reasonable. Very happy with the job and definitely recommend.

    Fantastic no hassle job completed by David and his team. This was 100mm insulation on a rented house. I was not on site all the time but could rely on a first class job. The tenant is delighted with a warmer house and reduction in heating bills just before the cost of energy increases!
